The front side of the coated duplex board with grey back presents a soft grayish-white tone with precise grayscale control, while the backside core is a uniform dark gray with a rough texture, enhancing the paper's adhesion performance and compatibility with any paper lamination needs. It meets the color and stiffness requirements in packaging design, with structural stability sufficient to meet the mechanical performance demands of most packaging scenarios, performing stably during regular stacking and transportation.

This product is made from 100% post-consumer waste paper pulp, achieving resource recycling at the raw material stage, reducing wood consumption by about 70% and water usage by 50% compared to traditional virgin pulp paper, deeply aligning with the EU CEFLEX initiative and domestic 'dual carbon' policy orientation, providing core material support for a green supply chain system.

The coating surface demonstrates excellent compatibility in print adaptability, providing good matching for halftone reproduction in offset printing, color saturation in flexographic printing, line clarity in gravure printing, and surface gloss in UV printing. The surface smoothness is controlled between 200-300 seconds (Bekk method), ensuring that the color reproduction rate exceeds 90% during 4-6 color overprinting, meeting the printing needs of intricate patterns and text information. The gray backside is more suitable for lamination on various materials such as paper and fabric and so on.

The weight covers a full range of specifications including 230gsm, 250gsm, 300gsm, 350gsm, 400gsm, and 450gsm, where 230-300g is suitable for lightweight packaging such as cosmetic inner liners and electronic accessory hangtags, while 350-450g meets the high-strength needs for heavy-duty corrugated box face paper and appliance cushioning pads, providing flexible choices for diverse packaging designs.

With its comprehensive performance, it is widely used in single-layer folding paper boxes (for food, daily necessities, etc.), corrugated composite cartons (e-commerce logistics packaging), supermarket promotional cards, clothing hangtags, among other fields, providing stable material solutions for fast-moving consumer goods packaging and industrial product identification.

This product has passed FSC Recycled 100% forest certification (ensuring 100% post-consumer waste paper source), EUDR easier traceability, DDS EU due diligence and other regulatory certifications (complying with cross-border trade environmental standards), SGS physical property testing (including burst strength, fold endurance, and 16 other indicators) and MSDS chemical safety data sheet filing, possessing international competitiveness in quality traceability and safety compliance. In terms of cost control, it has a 15-20% price advantage over similar coated white cardboard, although its surface gloss is slightly inferior to coated products, its environmental attributes and multifunctional adaptability form a comprehensive value, making it an optimal high-performance-to-price ratio packaging material solution.

Note: Due to the batch differences in de-inked pulp and waste paper, there may be slight differences in fiber distribution and color between batches, which is a normal phenomenon for this product.
